LM 7912 CT

Please do not continue without learning the specifications. A very basic Voltage regulator circuit is shown below. Initial value depending on the input 8.

W Watts which needs a good heatsink, otherwise thermal shutdown. LM Negative Voltage Regulator. There are many other ways in which the IC can be used based on your application.

I think it will become alright. The input voltage from the transformer is 28VAC pm7912 it is rectified and the l7m912 to the regulator becomes almost 42VDC. Thank you for your kind help. Is the device hot? Potentiometer with Microcontroller 3. Please let me KNOW is it because of regulator or some other component.? Skip to main lj7912. Whenever the unit is switched on for some time the output of the DAC is going 45mA which is out of our scaling. You are right the input voltage including spikes must not exceed 30V.

The value of the capacitors need not be the exact values, you can use the closest value you have got. Buffered Shunt Regulator as VRef – setting resistor values? But i have to test it for long time. There is no linearity between input mAmps and output mAmps.

LM belongs to the family of Voltage regulators. Top menu About Lm792 Contact. Initial and final energy stored in a capacitor You can also check on 78 series for positive voltage regulators. Since it is proved project i did not check the specifications.

I think it works. Hence, I have interchanged the polarity of the battery. The Input and output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively. Why Center Tap is used?

LM regulator output is setting down to zero Thank you for reply. You are using a bridge lm7192 circuit. Rating capacitors for safe voltages is the very basic rule. Mathematical formula of the minimum separations required between two patch antennas?

LM regulator output is setting down to zero If it gets too hot then it will shut down again. Last edited by SunnySkyguy; 25th August at My project is the sensor from the field will give 8 to 48 mA output and which is read by the ADC. The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter. Is the input voltage OK? LM regulator ouptut is setting down to zero Thank you for your kind reply. LM regulator output is setting down to zero Hi, maybe the overvoltage caused a “little” damage on the
